Available now on auction by Second Vintage This Seiko Lord Matic is a refined example of Japanese watchmaking from the mid-1970s, presenting a distinct aesthetic deviation from the standard stick indices typically found on this model.

The Lord Matic line was positioned just below King Seiko in the hierarchy, offering high-grade movements and superior finishing, making this a highly collectible piece for enthusiasts who appreciate the intersection of reliability and elegance. Brand: Seiko Model: Lord Matic Reference Number: 5606-8031 Serial Number: 510410 Movement: Seiko Caliber 5606 Automatic Dial: Silver sunburst with black Roman numerals Case Size: 36 mm Case Material: Stainless Steel Production Year: 1975 Condition: Good vintage condition, with a very well-preserved dial and honest wear to the case. Timegrapher results provided below. Dial and Hands The silver sunburst dial is in excellent condition, retaining a bright and metallic sheen that catches the light beautifully. The defining feature of this example is the full set of black Roman numeral hour markers, which are crisp and legible, providing a striking contrast against the silver background. The applied "SEIKO" and "LM" logos are intact and polished. The slender black stick hands match the indices perfectly, creating a cohesive and elegant look. A framed day-date window is positioned at 3 o'clock, adding practical utility to the sophisticated design. Case and Crystal The stainless steel case measures 36mm and features the classic Lord Matic case geometry with gently curving lugs and a polished finish. The case is in honest vintage condition, showing surface scratches and marks consistent with age and use, but retaining its original lines without signs of over-polishing. The caseback creates a solid seal and clearly displays the reference and serial numbers, along with the "Water Resist-G" designation. The crystal is clear and presents well, allowing for an unobstructed view of the dial. Movement Inside beats the respected Seiko Caliber 5606, a 25-jewel automatic movement known for its reliability and use in higher-tier Seiko models of the era. The movement is clean and the rotor swings freely. Timegrapher testing indicates a rate of +58 to +65 seconds per day, which indicates a healthy movement offering operational vintage performance. Strap The watch is fitted with a reddish-brown leather strap featuring an embossed crocodile pattern. The rich color of the strap provides a warm contrast to the cool tones of the steel case and silver dial, enhancing the dress watch aesthetic. It is finished with a silver-tone buckle that suits the overall design. Condition This timepiece is in excellent vintage condition. The most critical component, the dial, is remarkably clean and free of significant aging or spotting. The case shows expected wear for a watch from 1975, with scratches present on the bezel and sides, adding character to its history. The movement is functioning, and the watch presents as a well-cared-for example of a classic reference. Dimensions With a case diameter of 36mm excluding the crown, the watch sits comfortably on a variety of wrist sizes, offering a classic mid-century profile. The lug width is standard, allowing for easy strap changes should the new owner desire a different look. Remarks The Seiko Lord Matic 5606-8031 with Roman numerals is a less common variation that brings a touch of European dress watch styling to the robust engineering of the LM line. It captures the essence of 1970s Seiko design philosophy—high style, excellent legibility, and mechanical competence. History Introduced in 1968, the Lord Matic series was essential in cementing Seiko's reputation for automated manufacturing of high-quality mechanical watches. Positioned between the mass-market models and the premium Grand Seiko and King Seiko lines, the LM series featured the sophisticated 5600 series movements, which were thinner and more advanced than their predecessors. This specific example dates to January 1975, representing the mature period of the Lord Matic's production run. / Second Vintage SKU: SEISWNZLA0000
